This paper reports on a study to investigate the psychometric properties of the Japanese version of the academic self-concept scale of the Dimensions of Self Concept (DOSC). The original version was designed to assess the six dimensions of academic self-concept levels of aspiration; anxiety; academic interest and satisfaction; leadership and initiative; identification versus alienation; and stress. College students (N=158) attending a private university in Tokyo participated in the study. Analysis suggests that the Japanese version of the DOSC Scale Form H is a multidimensional scale measuring the six hypothesized constructs of academic self concept. As colleges and universities accept students from other countries, students will begin to assimilate to a new culture. Educators need to be aware of how assimilation can lead to a change in how students appraise themselves. The DOSC Scale Form H can serve as a useful tool to help understand student attrition.
